dated Norembcr 30, 1869.

Moor- .IMPRovED HAY-Tannen.

he Schedule referred to in these Letters Patent and making part o: the same.V

To all whom Iit may concern:

Be it known that I, YJOHN G. PERRY, of Kingston, in the county of Washington, and State oflthode Island, have invented certain new and useful Improvements in Hay-Tedders, of which the following is a full, clear, and exact description, reference heilig had to the accompanying drawings, which make part ci' this specification, and in which- Figure l is a plan or top view of a machine embracing my improvements.

Figure 2, a view, in elevation, of one side of the same.

Figure 3,a vertical longitudinal section through the same, at the line xtc of lig. l.

lFigure 4, an end viewof the countershaft and its shifting-level'.

Theobj'eetsof--rny invention are-to secure a compact arrangement of the mechanism, and tomove the teeth properly to seize' and stir the grass wit-hout throwing' it forward over the reel; and the mechanism hereinafter described embodies the imprm'ements I have devised for attaining these results.

In the accompanying drawings, the frame of the mechanism is shown as consisting of two thi-lis, A` A1, connected by cross-bars A2. 4

Two driving-wheels, B B', are mounted loosely on au axle, (l, with which they are locked, when the ma known construction, which arrangement permits the machine to be backed without working the reel.

The axle C also revolves in proper bearings in the fran'ie-work.

A. bevel-wheel, D, fast on the axle, drives a corresponding pinion, d, on a countershaft, E, which carries on its rear end a bevelgear,f, meshing into a eorrespondixig pinion, g, on a shaft, G, mounted, in proper bearings, on the rear ends of the thills A A.

The driving-wheels, and the main bevel-wheels, it will be observed, are arranged betweenthe thills.

' The countershaft E is arrangedY longitudinally be l neath the thill A1, and has a slight playin its rear bearingr e, while its front end is mounted eccentrically ina block, e', turning in a bearing, and controlled by a shipping-lever, E. By this means, when the shipping-lever is in the position shown in dotted lines in lig. 4,"the gears 1) il are disconnected, and when the lever is raised, as in figs. 1, 2, and 4, the mechanism is in gear.

A disk, H, is fixed on one end of the reel-shaft G, inside the thills, and a ring, I, vconnected with the reel-shaft by arms i, is fixed on the outer end oi' said shaft.

The rinor I revolves around a disk J fixed on the- The rock'shai'ts K carry spring-teeth M, and ther groove Lis so shaped that the teeth are caused tol project beyond the periphery of the disk H, when moving backward, as on the lower half of their Circuit, so as to stir and spread the hay, but are tumed inward and backward when moving ibrward on the up per portion of their circuit, and the rock-shafts can thus be arranged close to the dliving-wheels, without the teeth coming in contact with them.

In operation, as the n'iachine advances over the field, the driving-wheels revolve and communicate mo` tion to the shaft G,tbrough the gearing, andthe rockshafts K revolve with this shaft, during which move ment they are also rocked in their bearings by means of `the cranks f, [which traverse the camgroove L, as before described, so that as each bar descends toward the grass, its teeth will project downward to turn Aup the grass, but will be retracted as the teeth rise, and turned back so as not to throw the grass over to the front.

,I am aware that reels, wider than the distance hetweeu the driving-wheels, have heretofore been invented, and do not claim such arrangement.

\Vliat I claim as my invention, and desire to secure by 'Letters Patent, is

l. The combination of the thills, the loose drivingwheels, the revolving main shaft, its bevel-wheel, the revolving disk, the revolving ring, the cranked roekshafts carrying the teeth and the cam-groove, all constructed and operating substantially as setforth.

2. The combination of the revolving disk, the revolv'in g ring, the cranked rock-shaft carrying the teeth, the fixed disk, and the cam-groove, all constructed and operating as set forth.

3. In a hay-tedder, the cam-groove L, in combination with the cranked 'rock-shafts K, these parts being constructed to operate as and for the purposes speci: fied.
